防止 tcolorbox 位于页面底部

Question

有什么方法可以防止 tcolorbox 位于页面底部，而是自动将其推送到下一页？

梅威瑟：

\documentclass[a4paper, 10pt, oneside, twocolumn]{memoir}

\usepackage{tcolorbox}
\usepackage{lipsum}

\newtcolorbox{outcome}{before skip=2em, after skip=1em}

\begin{document}

\section{Sample}

\begin{outcome}
    This is some sample text. This is some sample text. This is some sample text. 
\end{outcome}

\lipsum[1-6]

This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. 

\begin{outcome}
    Sample text.
\end{outcome}

This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. 

\end{document}

Answer 1

尝试这个：

\makeatletter
\newtcolorbox{outcome}{before skip=2em, after={%
    \tcb@parfillskip@check\par\ifvmode\nointerlineskip
    \nobreak
    \addvspace{\glueexpr 1em-\parskip}\fi
    }}
\makeatother

after skip/.style该代码是从中的定义逐字复制的tcolorbox.sty，并#1用您的硬编码值替换1em，并\nobreak添加以使该框与下一段保持在一起。

Answer 2

这是我以前回答的一个方法这里：

\documentclass[a4paper, 10pt, oneside, twocolumn]{memoir}

\usepackage{tcolorbox}
\usepackage{lipsum}

\newsavebox{\mybottombox} % Box to save the text of the command 
\newlength{\mybottomlength} % The length of our text inside the command
\newlength{\availafter} % The available length left on the page after placing our text


% Optional argument is the minimum length after the nobottom text for not pagebreak. Change it to your needs
\newcommand{\nobottom}[2][60pt]{\savebox{\mybottombox}{\vbox{#2}}\setlength{\mybottomlength}{\ht\mybottombox}%
\setlength{\availafter}{\dimexpr\textheight-\mybottomlength-\pagetotal\relax}\ifdim\availafter<#1%
\pagebreak\noindent\usebox{\mybottombox}%
\else%
\noindent\usebox{\mybottombox}%
\fi%
}%

\newtcolorbox{outcome}{before skip=2em, after skip=1em}

\begin{document}

\section{Sample}

\begin{outcome}
    This is some sample text. This is some sample text. This is some sample text. 
\end{outcome}

\lipsum[1-6]

This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. 

\nobottom{%
\begin{outcome}
    Sample text.
\end{outcome}}

This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. This is some sample text. 

\end{document}
